Timolol maleate 0.5% versus timolol maleate in gel forming solution 0.5% (Timolol GFS) in open angle glaucoma in India. Preliminary safety and efficacy study.

PURPOSE: To compare the efficacy and safety profile of Timolol maleate 0.5% versus Timolol gel forming solution (GFS) 0.5% in open angle glaucoma in Indian eyes. METHODS: In a prospective crossover study 52 patients of open angle glaucoma, well controlled intraocular pressure (IOP) on 0.5% timolol maleate solution were switched over to timolol GFS once a day, after a washout period of one month. A diurnal IOP measurement was done after 6 weeks and compared with patients on timolol maleate 0.5% twice a day. In addition, side effects reported or observed were compared. RESULTS: Statistically significant difference was not observed in ocular hypotensive effect of the two treatment. The side-effects in both the treatment groups were similar except for higher incidence of blurring of vision in patients on timolol GFS. The compliance was better with timolol GFS, but was not statistically significant. CONCLUSION: The results of this study suggest that the more convenient 0.5% timolol in gel forming solution can be offered as an equally efficacious and well-tolerated alternative to twice daily 0.5% timolol solution in open angle glaucoma.

Therapeutic keratoplasty for infectious keratitis: a review of the literature.

PURPOSE: This article provides a review of the literature on various aspects of therapeutic keratoplasty, including indications, techniques, complications and outcome, and its application in cases of infectious keratitis. METHODS: Various articles on therapeutic keratoplasty (including English- and non-English-language publications) were analyzed. Selection of the articles was based on a Medline search for articles using the key words therapeutic keratoplasty, penetrating keratoplasty, therapeutic keratoplasty for infectious keratitis, non-healing corneal ulcer, microbial keratitis, and perforated corneal ulcer. Abstracts in English were used for non-English articles. RESULTS: Therapeutic keratoplasty has a definitive role in the management of progressive bacterial, fungal, Acanthamoeba, and viral keratitis refractory to medical treatment. Management of bacterial keratitis has higher functional success and anatomic cure rate compared with fungal, viral and Acanthamoeba keratitis. Therapeutic keratoplasty offers a cure rate of up to 100% in bacterial and fungal keratitis, whereas the recurrence of infection after Acanthamoeba keratitis is frequent. Visual outcome depends on various factors such as the causative agent, timing of surgery, degree of inflammation, type of donor material used, and size of the graft used. For example, larger grafts have a higher incidence of graft rejection and failure compared to smaller grafts. The primary aim of the procedure is to reestablish the integrity of the globe and to eliminate the infectious disease process. Visual rehabilitation is a secondary outcome. CONCLUSIONS: This review helps to elucidate the various aspects of therapeutic keratoplasty, including indications, preoperative assessment, surgical techniques, postoperative management, complications, and anatomic and functional outcome.

Inadvertent sclerostomy with encysted bleb following trans-scleral contact diode laser cyclophotocoagulation.

A 22-year-old woman underwent 360 degrees trans-scleral contact diode laser cyclophotocoagulation for refractory glaucoma. Conjunctival burns and scleral thinning were noticed inferonasally at the last laser application. Intraocular pressure in the first week was normal. Six months later the patient presented with encysted filtering bleb and high intraocular pressure. Ultrasound biomicroscopy revealed a full thickness sclerostomy. This report suggests that inadvertent sclerostomy may present with encysted bleb months after trans-scleral contact diode laser cyclophotocoagulation.

Atypical presentations of orbital cysticercosis.

We describe three patients with orbital cysticercosis who presented with atypical clinical or radiologic features previously unreported. All three patients had a cyst with a scolex on imaging studies. After 6 weeks of treatment, all three had almost complete resolution of their features.

Microbial keratitis after laser in situ keratomileusis.

PURPOSE AND METHOD: To review the literature on microbial keratitis reported after laser in situ keratomileusis (LASIK). RESULTS: Forty-one eyes have been reported to have microbial keratitis after LASIK. The causative organisms vary from gram positive bacteria to atypical mycobacteria, fungal, and viral pathogens. The infection is usually acquired intraoperatively, but may also be caused by postoperative contamination. A majority of the patients present within 72 hours of the surgery with an acute onset of symptoms. Management of microbial keratitis after LASIK includes aggressive topical fortified antibiotic therapy, irrigation of stromal bed with antibiotic solution after lifting the flap, and sending the scraping of the infiltrate for microbiological evaluation. The keratitis heals with scarring and a best spectacle-corrected visual acuity of 20/40 or better can be obtained in the majority of the patients. CONCLUSION: Microbial keratitis is a sight-threatening complication of LASIK.

Treatment of overhanging blebs with frequency-doubled Nd:YAG laser.

Large overhanging blebs can be associated with various complications (eg, overfiltration, endophthalmitis, and dellen formation). Argon laser treatment of such blebs has already been described. The authors used frequency-doubled Nd:YAG laser in 3 eyes of 3 patients with large filtering blebs. Gentian violet was used to stain the bleb surface and enhance the laser absorption. Laser spots were applied over the bleb surface. Bleb shrinkage and remodeling was observed in all 3 eyes. Intraocular pressure remained normal, suggesting that the filtering capability of the blebs was maintained.
